I created Heroku postres addon and added the db details to my config.js file. My model/index.js file looks like this:

"use strict";

var fs        = require("fs");
var path      = require("path");
var Sequelize = require("sequelize");
var basename  = path.basename(module.filename);
// Use env variable for our project.
var env       = process.env.NODE_ENV || "development";
// Read config from `config/config.js`;
// `node_modules/.bin/sequelize -c config/config.js cmd`
var config    = require(__dirname + '/../config/config.js')[env];
var sequelize = new Sequelize(config.database, config.username, config.password, config);
// Store the models.
var db        = {};

fs
  .readdirSync(__dirname)
  .filter(function(file) {
    return (file.indexOf(".") !== 0) && (file !== basename);
  })
  .forEach(function(file) {
    var model = sequelize["import"](path.join(__dirname, file));
    db[model.name] = model;
  });

Object.keys(db).forEach(function(modelName) {
  if ("associate" in db[modelName]) {
    db[modelName].associate(db);
  }
});

// Adds `sequelize` instance to db object.
db.sequelize = sequelize;

// Adds `Sequelize` class to db object.
db.Sequelize = Sequelize;

// Expose the db object.
module.exports = db;

My server.js looks like this:

// app dependencies
var morgan = require('morgan');
var methodOverride = require('method-override');
var bodyParser = require('body-parser');
var session = require('express-session');
var cookieParser = require('cookie-parser');
var express = require("express");
var isProduction = process.env.NODE_ENV === 'production';
var app = express();

//middleware
app.use(bodyParser.urlencoded({
  extended: true
}));
app.use(bodyParser.json({
    strict: false
}));
app.use(morgan(isProduction || 'dev'));
// static resources
app.use(express.static("./public"));
app.use(methodOverride());

// Use cookie middleware
app.use(cookieParser());
// Enable session management by express
app.use(session({
  secret: 'changethis!',
  resave: false,
  saveUninitialized: false
}));

// Init the models
var db = require("./models");

db.sequelize
  //You can set `force` to `true` in development mode.
  .sync({
        //force: true
    })
  //.sync()
  .then(function() {
    console.log('Express server listening on port 5000');
    app.listen(5000);
});


var auth_handler = require('./lib/auth/passport.js')(app, db.User);

// resources routes
// app.use('/', require('./routes/web'));
//app.use('/api', auth_handler, require('./routes/api'));
app.use('/api', require('./routes/api'));

// default route for website
app.use( function(request, response) {
  response.sendFile('./public/index.html', {root: __dirname});
});

Any idea whats going on?

Simply because I know I’m going to run into this again:

if (process.env.DATABASE_URL) {
  // the application is executed on Heroku ... use the postgres database
  sequelize = new Sequelize(process.env.DATABASE_URL, {
    dialect:  'postgres',
    protocol: 'postgres',
    logging:  true //false
  });
} else {
  // the application is executed on the local machine
  sequelize = new Sequelize("postgres:///my_db");
}

For Heroku

        var database = process.env.DATABASE_URL || 'campeonatodb'
        var sequelize = ""

        if (process.env.DATABASE_URL) {
            sequelize = new Sequelize(database)
        }
        else {
            sequelize = new Sequelize(database, 'postgres', '', {
                dialect: 'postgres'
            });
        }
